WHEEL.

SPECIFICATION forming part of Letters Patent No. 500,578, dated July 4, 1893.

Application tiled .Tuly 21, 1892.

To all whom t may concern..-

Be it known that I, FRANKLIN C. HooKEN- SMITH, of Irwin, in the county of Westmoreland and State of Pennsylvania, have invented a new and useful Improvement in Wheels, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specication, in which- Figure 1 is a faceview of my improved wheel with the cap removed. Fig. 2 is a central cross-sectional view of the same, and Fig. 3 is a detail view hereinafter referred to.

My invention relates to the construction of wheels wherein an oil-chamber is employed for affording a constant supply of oil to the axle of the wheel, and it consists in an improved construction of the parts whereby the capacity of the chamber is greatlyincreased, the flow of oil is rendered more steady and regular and the introduction of the oil is facilitated. Y

In the drawings, 2 indicates the periphery of a wheel, having spokes 3 and hub 4.. Gast integral with this hub is the annular case 5 surrounding the same and joined thereto by the radial web portions 6, the series of fins 7 and the continuous flange 8. Passing through the flange 8 is an oil-supply tube 9,which extends at an angle to the hub and terminates near the bottom of its concave or inwardly curved portion. It will be noticed that the mouth of the oil-tube 9 is formed on a horizontal line parallel with the fluid level of the oil-chamber, whereby the mouth of the tube is brought close to the bottom of the chamber, and the escape of oil therefrom through the tube is prevented. The cover 10 of the oil case or reservoir is secured to the inner face of the wheel by the hooked bolts 11, which take about the inner ends of the webs 6.

In the operation of my device the space between the webs is filled with woolen waste or similar material, it being held in place by the tins so as to leave a clear annular space in the rear into which the pipe 9 projects. There are two of the chambers, however, formed by the webs 6 which are left empty, as shown in Fig. 1, and into that portion of the annular space in the rear of these chambers passes the oil-supply pipe 9. The purpose of so leaving these spaces is to form a chamber in Which a supply of oil is main- Serial No. 440,762. (No model.)

tained Without danger of its escaping by the tube 9 when in its lowest position, and hence prevent the oil from rising so high as to iiow out of said tube. The oil which is poured in through the pipe 9 saturates t-he waste and passes, through the usual holes 12, which connect only with those spaces which are filled with waste, to the shaft and lubricates the same. The annular space in the rear of the waste, together with the unlled chambers, form a large supply reservoir, especially in connection with the curvature of the exterior of the hub, and the waste is easily replaced by removing thevcover 10. The location of the oil-tube prevents the entrance of dust and renders it easy to iill in the oil.

Without restricting myself to the precise construction shown, what I claim as new, and desire to secure by Letters Patent, is-

1. A wheel having an annular reservoir surrounding its hub, an annular cover having a hub band, and hook bolts arranged to secure the cover to webs in the reservoir; substantially as and for the purposes described.

2. A wheel, having a hub with a concave eX- terior surface, an annular reservoir surrounding the same, and a conduit leading from the reservoir at a point removed from th'e level of the base of the concavity to the axle; substantially as described.

3. A wheel, having an annular reservoir su rrounding its hub, a hub having concave exterior surfaces, an inclined oil-tube leading from the face of the wheel into the space formed by the concavity, the ymouth of the tube in the chamber being on a line substantially parallel with the level of the fluid in the space, and a conduit leading from the reservoir to the axle; substantially as described.

4. A wheel, having a hub with a concave eX- terior surface, an-annular reservoir surrounding said hub, a series of webs dividing aportion of the reservoir into separated spaces, radial fins arranged to hold a filling in these spaces, and a removable cover for the reservoir; substantially as and for the purposes described.

In testimony whereof I have hereunto set my hand this 11th day of July, A. D. 1892.
